XG Firewall Firmware Upgrade Failed: 17.5.15 MR-15 to 18.0.4 MR-4 / 18.0.5 MR-5

We are attempting to upgrade the firmware of Sophos XG310 unfortunately it is failing. Firmware v18.0.4 MR-4 is actually present in the backup partition but once we initiate the upgrade, the XG went back to its previous firmware version 17.5.15 MR-15.

We have attempted a few times with the same results.

  • Run upgrade from version 17.5.15 MR-15 to version 18.0.5 MR-5 is not successful
  • Tried to upgrade from version 17.5.15 MR-15 to version 18.0.4 MR-4 still not successful

2 methods we used to run the upgrade:

Definitely, upgrading from 17.5.15 MR-15 to 18.0.5 MR-5 should be supported quoted from this release notes. https://docs.sophos.com/releasenotes/index.html?productGroupID=nsg&productID=xg&versionID=18.0 

Any help/suggestions would be appreciated.

Regards,
Mike

  • There is a bug which sounds very much like you are experiencing, I've had it with two XG's (out of a large estate, it's quite rare but something you don't want).

    In the end we re-flashed the one with v18 and the other one is for someone that is unlikely to renew their license in a few months (so will fix itself I guess). Its reference is NC-61506, I'm afraid although it's been around for while there's no indication of a fix. We've not yet tried a v18 update to MR5.
